AB168 Panel Layout
Input sockets 16 balanced XLR mic/line
inputs with +48V Phantom Power indicator. The
preamps are built into the AB168 and their Gain,
Pad and 48V phantom power are remote
controlled from the mixer via the dSNAKE link.
The outputs of the analogue preamps are
converted to digital format and transported via
dSNAKE to be processed and mixed at the GLD
or Qu mixer.
The sockets are numbered 1-16. On GLD, any
input can be patched to any channel at the
console. On Qu, sockets are mapped one-to-one
to input channels.
The Phantom Power indicator detects voltage at
the socket whether supplied by the AB168 or
received from an external source.
Output sockets 8 balanced XLR outputs
operating at nominal +4dBu line level. Any signal
can be patched to any socket using the GLD
I/O
screen or Qu
Setup / Output Patch / dSNAKE
menu. The mixer defaults to a logical mapping of
these sockets to get you started.
Space is provided next to the sockets for
custom labelling.
dSNAKE port Cat5 cable link to connect to
the mixer or AR2412 rack. This carries the
inputs, outputs and the monitor sends to and
from the AB168 as well as preamp control and
system status. Maximum Cat5 cable length is
120m (396’) depending on cable type.
We recommend using EtherCon locking
connectors to prevent damage to cables or ports.
EXPANDER port Cat5 cable link to
connect a second AB168 rack to add further
mic/line inputs and XLR line outputs. It can also
be used to connect to the Allen & Heath ME
personal mixing system.
Mains power input IEC connector and
fuse for the built-in universal voltage power
supply unit. This accepts worldwide voltages
from 100 to 240V AC 50/60Hz. Check that you
have received the correct mains lead for your
territory.
Secure the cable in place using the plastic P-clip.
Use a T20 Torx screwdriver to refit the screw.
Vents Ensure good ventilation at the sides
and back of the rack. Avoid obstruction of vents
while operating. Avoid dirt or liquid ingress.
Note
Read the Safety Instructions Sheet and information printed on the panel before operating.
